An energetic storm system is set to sweep into the region from the southwest, drawing in a plume of tropical moisture that will feed downpours developing late Thursday (after midnight) and continuing into Friday morning. But, we may still see a few scattered showers and thunderstorms throughout the day as the cold front moves through.

The showers and storms will come to an end from west to east through Friday morning. Meteorologists also expect rainfall to produce water accumulations between 3 to 4 inches, with amounts higher in some areas.

High resolution Canadian: 1.7 inches.

The National Weather Service has issued a tornado watch for portions of the Carolinas until 3 a.m. on Friday. Warm high pressure will be replaced by a winter-like storm that could be packing rain, thunderstorms, wind and even some mountain snow.

The risk for severe weather is highly dependent on several different factors, which could increase or reduce the risk for powerful storms in Montana.
